Title: Procedimiento para la epoxidacion de una olefina
Inventor: BULL RANDY ALAN
IPC: C07B61/00
Filed: 1986-03-10
Abstract: La presente invención se refiere a un procedimiento para la epoxidación de una olefina a fin de formar el oxirano correspondiente, caracterizado por los pasos de: (a) formar una mezcla de reacción incorporando una olefina, un anhídrido cíclico de un ácido carboxílico polibásico y un catalizador básico en un solvente inerte no acuoso, el solveente tiene una temperatura de ebullición considerablemente mayor que la temperatura de ebullición del oxirano de la olefina, y el anhídrido se incorpora en una cantidad suficiente para mantener la mezcla de reacción esencialmente anhídra, (b) incorporar peróxido de hidrógeno en la mezcla de reacción, a un régimen controlado para evitar acumular un exceso considerable de peróxido de hidrógeno en la mezcla de reacción, convirtiendo de esta manera por lo menos parte de la olefina en el oxirano correspondiente y por lo menos parte del anhídrido cíclico en un ácido carboxílico polibásico correspondiente, y (c) recuperar el oxirano como un destilado del producto del paso (b) y dejar una solución residual del a´cido carboxílico polibásico en el solvente inerte.

Inventor: LEDENT MICHEL ALEX OMER
IPC: C07F9/38
Filed: 1981-08-31
Abstract: Solutions of aminomethylenephosphonic acids derived from diethylenetriamine and containing diethylenetriaminepenta(methylenephosphonic acid) as a principal Component are commercial products useful as metal sequestrants. Known solutions, which usually contain not more than 9% by weight of hydrochloric acid, show a tendency to deposit solid aminomethylenephosphonic acid on storage. This tendency is overcome by increasing the mineral acid content of the solution to 10% or more of hydrochloric acid by weight of the solution or an equivalent amount of at least one other non-oxidising mineral acid.

Abstract: The display device comprises a cell having two levels, between two polarizers 1 and 7, the directions of polarization of which are at an angle of 120 DEG  to each other. The two-level cell comprises two liquid crystal layers 5 and 6, each of which, in the rest condition, causes rotation of the plane of polarization of the light through 60 DEG . The orientation of the molecules of the input surface of the first layer 5 is parallel to the direction of polarization P1 of the first polarizer 1. The orientation of the molecules of the input surface of the second layer 6 is parallel to the orientation of the molecules on the output face of the first layer 5.
